NIGP 30564: Opaquing and Transparentizing Liquids, Erasing Fluids, and Pastes

NIGP 30564 Opaquing And Transparentizing Liquids, Erasing Fluids, And Pastes is an Item code under which state and local governments procure specialty fluids and compounds for maintenance, fleet operations, and facility management. The recent solicitation activity shows that this code captures industrial and automotive fluids — specifically, antifreeze and coolants — rather than the literal opaquing or erasing products the legacy NIGP name suggests. State and local issuing bodies under this code include municipal fleet operators, transportation departments, and city purchasing offices acting on behalf of operating agencies. The City of Detroit Office of Contracting and Procurement solicits under this code for its Department of Transportation fleet maintenance needs, indicating that municipal transportation authorities and city procurement offices are active buyers.

The most recent opportunity centers on Detroit's RFQ for low silicate, phosphate-free, inhibited ethylene glycol antifreeze in both concentrate and premixed formulations, posted September 25, 2026, with quotes due October 9, 2026 at 1:00 p.m. EST. Detroit estimates annual consumption of approximately 24,000 gallons split across four line items (premixed and concentrate in both drums and bulk delivery), with contract term of two years and optional renewal subject to City Council approval. Respondents must be current commercial antifreeze formulators or authorized dealers, carry minimum $1,000,000 liability insurance, hold Michigan hazardous-materials transportation licensing, and deliver within three business days of order. Detroit-based and small-business certifications receive equalization credits of one to five percent. The source does not reveal other recent state or local opportunities under this code or activity in other jurisdictions.
